I've had my blaze for around 20 months and love it. Over the last week the heart rate monitor is wildly out. Saying mid HIIT workout I'm at 82.....before I was in the 140-150 zone.

 

I've tried switching off, charging, wearing it higher on wrist, tighter, looser, you name it.

 

Can someone please help? This is a massive reason why I bought this product so a bit upset that its stopped working properly.

I have a similar issue. Before Christmas, my Blaze was showing a lot of peak and cardio rates on my daily bike rides. (I'm talking about numbers, not zones). Today, powering up a steel hill (according to the exercise analysis) barely got me to the rate I reach during a brisk walk. My own perception of my pulse during that part of the ride says otherwise!

 

According to my device, I spent more time at a cardio level sitting on my couch yesterday.
